Standard Operating Procedure: Utility Truck Waste Handling Date: 6/22/2015* Version: 1 Review Frequency: Annual

Reasons for Procedure The University of Virginia (UVA) has a permit to operate a Municipal Separate Storm Sewer System (MS4) issued by the Virginia Department of Environmental Quality. This permit authorizes UVA to discharge stormwater pursuant to the Virginia Stormwater Management Program and the Virginia Stormwater Management Act. UVA operates a vacuum truck that is used to clean out storm drains and other utility structures and excavations. Proper management of the material collected is required to insure that entrained contaminants are not introduced into the environment, specifically waterways.

1.0 Purpose This document outlines the proper procedures for the management of the wastes collected by the utility vacuum truck operated by Facilities Management employees.

2.0 Scope

This procedure applies to all FM employees that are responsible for the management and operation of the vacuum truck.

3.0 Responsibility All UVA staff are responsible for preventing illicit discharges from their operations. Water contaminated with detergents, debris, chemicals, soils, and other waste products must not be disposed of via the storm sewer system.

3.1 Facilities Management Environmental Resources

Environmental Resources (ER) is responsible for working with staff to keep this policy up to date and revised as needed.

3.2 Managers and Supervisors

Shop Managers and Supervisors are responsible for ensuring their staff’s compliance with this procedure. Managers are to train their employees on how to prevent potential illicit discharges from their operations and how to dispose of wastes properly. Managers must also instruct their contractors who perform vacuum truck work about these requirements. Managers and supervisors are responsible for ensuring training is conducted with the most recent version of the SOP. Utility Vacuum Truck Waste Handling

3.3 Personnel Performing the Job

Personnel must follow the correct procedures in accordance with this SOP. Specific responsibilities are explained in the procedures.

4.0 Procedures 4.1 Truck Material Discharge Options

Material Discharge Options

Storm sewer system wastes Transfer facility and/or landfill

Gravel & Other Construction Debris CDD landfill or temporary storage at FM Yard at Old Ivy Road

Sanitary wastes, truck rinse water Moores Creek Treatment Plant or UVA

Any other materials Consult Environmental Resources

NOTE: Oil-water separators are NOT to be cleaned out using the vacuum truck. These wastes should be removed by an outside contractor.

4.2 General Storm Sewer Waste 4.2.1 Storm sewer cleaning waste consists of general debris that collects in storm drainage systems and includes materials such as litter, leaves, soil, sand, gravel, and other general urban wastes. 4.2.2 Leaves, mulch, and other naturally derived organic matter can be taken to the compost yard on Observatory Hill and placed in the leaf composting area. There cannot be any other litter or trash in this material and it cannot contain free liquids (i.e., it cannot be dripping wet). 4.2.3 All other loads of storm sewer wastes are to be taken to the FM yard on Old Ivy Road and placed in the Vacuum Truck Transfer Station. This station is designed to provide for some dewatering of the material as well as staging for loading into trucks for transport to permitted waste disposal facilities off campus. Dewatered organic matter free of trash may be transferred to the landscape compost yard located on Observatory Hill. 4.2.4 The only outdoor location for disposal of non-hazardous waste water, such as decant water from the vacuum truck, is in the sanitary sewer at the Washing Station at the FM Leake Yard. 4.2.5 Waste water from oil-water separators shall not be put in the vacuum truck. An outside contractor must be used for these maintenance operations.

4.3 Vacuum Truck Transfer Station 4.3.1 The Vacuum Truck Transfer Station is located at the FM Yard on Old Ivy Road and is designed to allow for the dewatering of the delivered waste through gravity separation and evaporation. 4.3.2 The station is made of concrete and has side walls to prevent runoff from the waste from leaving the containment area while preventing run-on into the station from the surrounding areas. 4.3.3 The wastes should be spread out within the basin so the materials will dry more quickly. 4.3.4 Waste collected in the facility will be loaded on trucks or placed in a dumpster for disposal at an appropriate permitted waste disposal facility. Dewatered leafy debris free of trash may be taken to the University’s composting yard. 4.3.5 Wastes must be removed from the facility at a frequency that will prevent liquid or solid waste from overflowing the containment area either from excess quantities of waste or weather events. 4.3.6 If accumulated rainwater is pooling in the waste unloading section of the station, use the vacuum truck to remove the rainwater before transferring storm sewer wastes into it. This water must be discharged to the sanitary sewer due to potential contamination from residual pollutants within the containment area.

4.4 Gravel and Other Construction Debris 4.4.1 Gravel and other spoils from construction sites may be temporarily stored at the Old Ivy laydown yard if appropriate erosion and sediment controls (E&SC) are used, such as silt fence and/or tarps. 4.4.2 All E&SC measures must be installed, routinely inspected, and maintained in accordance with the standards and specifications in the current Virginia E&SC Handbook (http://www.deq.state.va.us/Programs/Water/StormwaterManagement/ Publications/ESCHandbook.aspx). 4.4.3 Gravel free of is non-erodible and does not need E&S controls installed. 4.4.4 Construction debris and spoils should be transferred to a permitted waste disposal facility as soon as practical.

4.5 Sanitary Wastes 4.5.1 Sanitary wastes may only be discharged back into the UVA sanitary sewer system or at the Moores Creek Plant.

4.5.2 After handling sanitary wastes, the truck’s holding chamber will be washed. The wash water will be managed the same as the sanitary waste.

4.6 Other Wastes and Wastewater 4.6.1 Other wastes and wastewaters collected in the vacuum truck could include spilled materials that normally would not be found in storm drainage systems. 4.6.2 The disposal of all other wastes will be done on a case by case situation through consultation with Environmental Resources and/or the Office of Environmental Health and Safety. The disposal of waste water or chemical residue outdoors violates the University’s Stormwater Discharge Permit.

5.0 Annual Review of Procedure/Training Managers are responsible for reviewing this procedure at least once each year with all employees who have these job duties.

6.0 Regulatory impacts

Discharges of any material other than stormwater are prohibited by the University’s MS4 permit and by the City of Charlottesville’s Water Protection Ordinance. The University’s storm sewer system is directly connected to the City’s; therefore, any discharge into UVA’s storm system impacts the City’s storm sewer system. This offense is punishable by civil and criminal penalties as illicit discharges constitute a threat to the public health, safety, and welfare, and are deemed public nuisances. Proper handling and disposal of landscape wastes will help keep this material out of the stormwater drainage network.
